Welcome to Wikipedia. I saw that you edited or created Berlin Mathematical School, and I noticed that your username, "BerlinMathematicalSchool", may not comply with our username policy. Please note that you may not use a username that represents the name of a company, group, organization, product, or website. Examples of usernames that are not allowed include "XYZ Company", "MyWidgetsUSA.com", and "Trammel Museum of Art". However, you are invited to use a username that contains such a name if it identifies you personally, such as "Mark at WidgetsUSA", "Jack Smith at the XY Foundation", and "WidgetFan87".

Please also note that Wikipedia does not allow accounts to be shared by multiple people, and that you may not advocate for or promote any company, group, organization, product, or website, regardless of your username. Moreover, I recommend that you read our conflict of interest guideline. If you are a single individual and are willing to contribute to Wikipedia in an unbiased manner, please create a new account or request a username change that complies with our username policy. If you believe that your username does not violate our policy, please leave a note here explaining why. Thank you. WikiDan61^ChatMe!_ReadMe!! 14:46, 28 April 2015 (UTC)[reply]

Hello. A bureaucrat or clerk has responded to your username change request, but requires clarification before moving forward. Please follow up at your username change request entry as soon as possible. Thank you. --I am k6ka ^{Talk to me!} _{See what I have done} 16:54, 28 April 2015 (UTC)[reply]

Welcome to Wikipedia. Because we have a policy against usernames which give the impression that the account represents a group, organization or website, I have blocked this account; please take a moment to create a new account with a username that represents only yourself as an individual and which complies with our username policy or request a change of username.

You should also read our conflict of interest guideline and be aware that promotional editing is not acceptable regardless of the username you choose. Additionally, if your contributions to Wikipedia form all or part of work for which you are, or expect to be, paid, you must disclose who is paying you to edit.

Please also note that you are permitted to use a username that contains the name of a company or organization if it identifies you individually, such as "Sara Smith at XYZ Company", "Mark at WidgetsUSA", or "FoobarFan87".

If your username does not represent a group, organization or website, you may appeal this username block by adding the text {{unblock|reason=Your reason here ~~~~}} at the bottom of your talk page.

You may simply create a new account, but you may prefer to change your username to one that complies with our username policy, so that your past contributions are associated with your new username. If you would prefer to change your username, you may appeal this username block by adding the text

{{unblock-un|new username|reason=Your reason here ~~~~}}

at the bottom of your talk page. Please note that you may only request a name that is not already in use, so please check here for a listing of already taken names.

 Thank you. Glen (talk) 12:00, 25 September 2020 (UTC)[reply]
